dt-bindings: drop redundant part of title (end)

2022-12-16T17:41:49Z

The Devicetree bindings document does not have to say in the title that it is a "Devicetree binding", but instead just describe the hardware. Drop trailing "Devicetree bindings" in various forms (also with trailing full stop): find Documentation/devicetree/bindings/ -type f -name '*.yaml' \ -not -name 'trivial-devices.yaml' \ -exec sed -i -e 's/^title: $.*$ [dD]evice[ -]\?[tT]ree [bB]indings\?\.\?$/title: \1/' {} \; find Documentation/devicetree/bindings/ -type f -name '*.yaml' \ -not -name 'trivial-devices.yaml' \ -exec sed -i -e 's/^title: $.*$ [dD]evice[ -]\?[nN]ode [bB]indings\?\.\?$/title: \1/' {} \; find Documentation/devicetree/bindings/ -type f -name '*.yaml' \ -not -name 'trivial-devices.yaml' \ -exec sed -i -e 's/^title: $.*$ [dD][tT] [bB]indings\?\.\?$/title: \1/' {} \; Signed-off-by: Krzysztof Kozlowski Acked-by: Alexandre Belloni Acked-by: Jonathan Cameron # IIO Reviewed-by: Jonathan Cameron Acked-by: Ulf Hansson # MMC Acked-by: Stephen Boyd # clk Acked-by: Dmitry Torokhov # input Acked-by: Mark Brown Acked-by: Hans Verkuil # media Acked-by: Sebastian Reichel # power Link: https://lore.kernel.org/r/20221216163815.522628-5-krzysztof.kozlowski@linaro.org Signed-off-by: Rob Herring

dt-bindings: dma: ti: Add missing ti,k3-sci-common.yaml reference

2021-12-17T16:09:27Z

The TI k3-bcdma and k3-pktdma both use 'ti,sci' and 'ti,sci-dev-id' properties defined in ti,k3-sci-common.yaml. When 'unevaluatedProperties' support is enabled, the follow warning is generated: Documentation/devicetree/bindings/dma/ti/k3-bcdma.example.dt.yaml: dma-controller@485c0100: Unevaluated properties are not allowed ('ti,sci', 'ti,sci-dev-id' were unexpected) Documentation/devicetree/bindings/dma/ti/k3-pktdma.example.dt.yaml: dma-controller@485c0000: Unevaluated properties are not allowed ('ti,sci', 'ti,sci-dev-id' were unexpected) Add a reference to ti,k3-sci-common.yaml to fix this.

dt-bindings: Add missing 'unevaluatedProperties'

2020-10-07T16:26:41Z

This doesn't yet do anything in the tools, but make it explicit so we can check either 'unevaluatedProperties' or 'additionalProperties' is present in schemas. 'unevaluatedProperties' is appropriate when including another schema (via '$ref') and all possible properties and/or child nodes are not explicitly listed in the schema with the '$ref'. This is in preparation to add a meta-schema to check for missing 'unevaluatedProperties' or 'additionalProperties'. This has been a constant source of review issues.

dt-bindings: Remove cases of 'allOf' containing a '$ref'

2020-05-03T16:10:41Z

json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$ref' are ignored (silently). The correct form was to put a '$ref' under an 'allOf'. This behavior is now changed in the 2019-09 json-schema spec and '$ref' can be mixed with other keywords. The json-schema library doesn't yet support this, but the tooling now does a fixup for this and either way works. This has been a constant source of review comments, so let's change this treewide so everyone copies the simpler syntax. Scripted with ruamel.yaml with some manual fixups. Some minor whitespace changes from the script.

dt-bindings: Clean-up schema indentation formatting

2020-04-16T21:59:22Z

Fix various inconsistencies in schema indentation. Most of these are list indentation which should be 2 spaces more than the start of the enclosing keyword. This doesn't matter functionally, but affects running scripts which do transforms on the schema files.

dt-bindings: dma: ti: k3-udma: Update for atype support (virtualization)

2020-03-02T09:14:06Z

In UDMA each channel can use different ATYPE value which tells UDMA how the addresses in the descriptors should be treated: 0: pointers are physical addresses (no translation) 1: pointers are intermediate addresses (PVU) 2: pointers are virtual addresses (SMMU) When virtualized environment is used then the dma binding should use additional cell to configure the desired ATYPE for the channel.
